Merge tag 'topic/drm-header-rework-2014-09-12' of git://anongit.freedesktop.org/drm-intel into drm-next

So here's the header cleanup, rebased on top of drm-next. Two new header
files are created here:

- drivers/gpu/drm/drm_internal.h for non-legacy drm.ko private
  declarations.

- include/drm/drm_legacy.h for legacy interfaces used by non-kms drivers.

And of course lots fo stuff gets shuffled into the already existing
drivers/gpu/drm/drm_legacy.h for drm.ko internal stuff.

topic branch smoke-tested in drm-intel-nightly for a bit. And the 0day
tester also worked through it (and found a few places I didn't add a
static to functions).
